Abstract
3 - Acetamido - 4 - methoxy-benzene - N - substituted sulphonamides are prepared by refluxing 3-acetamido-4-methoxy-benzene sulphochloride with a primary amine in dioxane. The primary amine may be n-butylamine, aniline or p-methoxy aniline. These compounds may be refluxed with methanolic hydrogen chloride to give the corresponding 3-amino-4-methoxy-benzene -N-substituted sulphonamides. The 3-amino group may then be acylated with beta-ketoacetic esters to give 3-acyl-acetylamino derivatives wherein the acyl group is benzoyl, p-methoxybenzoyl, acetyl or thenoyl.
